Why diners never go out of business

Diners survived by refusing to compete on excellence. While restaurants gravitated to off-premise dining, small menus, originality and automation, diners kept the 1940s formula — huge menus, open 24/7, pen-and-paper service, and no pretense of quality. The customer is not asking for reinvention.

The menu is built on carbohydrates on purpose. Most restaurants center on protein and are therefore exposed every time protein prices move. Diners position carbs as the star, satiate customers cheaply, and are structurally insulated from the commodity swings that force other restaurants to reprice.

The low expectations are the margin. Frozen premade patties, liquid eggs, tubbed soup, frozen vegetables and packaged desserts would shame an independent restaurant. At a diner they are simply the product, because customers arrive expecting cheap, simple and consistent.

Denny's is the oldest diner chain in the world and the most proactive of the three, with over 1,600 locations, 90% of them in the United States, 96% franchised, in freestanding 4,400 sq ft buildings seating 140.

Denny's treats franchisees as partners, which is genuinely rare. Every franchisee joins the Denny's Franchisee Association, which runs five committees — Development, Marketing, Operations, Supply Chain and Technology — collaborating directly with corporate. The equivalent bodies at Burger King and KFC are self-organized and carry no official recognition.

Denny's sees fast food, not other diners, as its competition — and reacts to it. It only replaced the water in its pancake mix with eggs and buttermilk after McDonald's launched all-day breakfast in 2015, then promoted the result as 50% fluffier.

None of the proactivity moved the number. The average Denny's franchise grossed $1.3M in 2010 and $1.7M by 2022; blended across ownership types the average location went from $1.6M in 2011 to $2.3M in 2022 — 46% over eleven years, or 3-4% a year. Locations went from 1,685 in 2011 to roughly 1,600 by 2022.

The check is the ceiling. A Denny's guest spent $10.89 in 2019 before tax and tip, well below Olive Garden, the Cheesecake Factory or BJ's Brewhouse. High margins on tiny checks still produce very few dollars.

Labor, not food, is the constraint. A single Denny's runs on 50 people across two shifts, and labor has averaged 39% of sales over the past decade against food costs of 25%. The $70-80M advertising warchest returns $47 in sales for every $1 spent.

Cracker Barrel rejected franchising outright on the belief that food and service can only be held to standard through control — so it has just 664 restaurants and opened only 69 in twelve years, against Denny's 1,600-plus. 80% sit alongside highways to catch travelers.

It is also a retail business wearing a restaurant. Of 8,900 sq ft, 1,900 is shop floor, and customers enter and exit through it. Retail is a $700M business at 50% gross margins, contributing 20% of revenue — a high-margin supplement propping up a low-margin restaurant.

And it lands in exactly the same place. Cracker Barrel's store-level operating margin is 13%, identical to Denny's — Denny's inflated by the survivorship bias of its few remaining high-performing corporate stores, Cracker Barrel's propped up by retail. Growth from 2010 to 2019 averaged 2.9% a year.

IHOP is the largest diner chain in the world, over 1,700 locations, all franchised or licensed, and it has been neglected for over a decade while Dine Brands was preoccupied with saving Applebee's.

Dine Brands extracts from IHOP franchisees three ways — a 4% royalty, a markup on the proprietary pancake mix operators are required to buy daily, and a markup on the rent for buildings it leases them — plus 3.5% of gross sales for advertising. It offers no site selection help, no financing options, and requires everything paid upfront in full.

It worked beautifully for the franchisor and barely at all for the franchisee. Dine Brands took nearly $200M a year out of IHOP at over 80% gross margins, growing 4% annually for twelve years — while the average IHOP grossed just $1.9M in 2022 and grew total sales 9% in twelve years. The company stopped reporting average check after 2015, when it was $11.53.

The conclusion is the same in all three directions. Proactive investment, refusal to compromise, and outright neglect all produce a 13% store margin and low single-digit growth. Certain businesses are so commoditized that strategy cannot make them grow fast, and nothing can make them die.
